TOOTH FOR HAY-RAKES.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed January 11, 1913. Serial No. 741,552,

To all whom it may concern Be it known that I, HJAnMAn Tononnsnn, a citizen of the United States, residing at Ashby, in the county of Ottertail and State of Minnesota, have invented a new and useful Tooth for Hay-Rakes, of whlch the following is a specification.

This invention relates to hay rakes and more particularly to teeth therefor, the same being designed especially for use in connection with hay rakes such as shown, for example, in Patent 1901,90 1, issued tome on August 29, 1911.

One of the objects of the invention is to provide a spring tooth so constructed that, when a number of teeth are connected to the same supporting bar, any one of said teeth is free to spring upwardly, when striking an obstruction, without producing a corresponding movement of the remammgteeth.

A further object is to provide a spring tooth which will yield readily and which is so shaped as to prevent hay or the like from working up against the supporting bar or against the rearwardly extending portion of the tooth and clogging the rake.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings: Figure 1 is a front ele vation of a portion of a bar having a series of teeth attached thereto. Fig. 2 is a section on line A-B Fig. 1. Fig. 3 is a plan view of the structure shown in Fig. 1.

Referring to the figures by characters of reference 1 designates the downwardly and forwardly curved back portion of the tooth the same being formed of stiif spring wire and provided at its lower end with an upwardly extending curved finger 2, this finger curving backwardly and thence forwardly and gradually diverging from the back portion of the tooth. The upper end of the portion 1 merges into a loop or eye 3 and from this eye extends a forwardly projecting arm 4 the front of which merges into a coil 5. This coil has a terminal eye 6 which may be engaged by a pin 7 or other suitable holding device engaging a rod 8 or other structure extend-ed loosely through the coil 5.

It is to be understood that a series of these teeth may be mounted upon the rod 8 or other supporting structure provided and, when the rake is drawn forward, the hay or other material being gathered will press against the finger 2. and, as this finger is curved upwardly and forwardly toward the coil 5, it will be seen that the material will be prevented from packing against the arm 4% and will be rolled forwardly. F urthermore, as the entire device is made of a single length of spring wire, it will be seen that should one of the teeth strike an unyielding obstruction, the said tooth can spring upwardly and backwardly without elevating the other teeth, this being permissible in view of the fact that the arm 4 of the tooth will yield under such conditions.

What is claimed is The combination with a supporting structure, of a tooth formed in a single length of spring wire and including an arm extending rearwardly from said structure said arm having a coil at its forward end, said coil extending loosely around the supporting ele ment and terminating in an eye, means extending through the eye and from said supporting element for holding the coil against rotation upon said element, a single loop at the other end of the arm, a downwardly and forwardly curved projecting yielding portion extending from the loop, and a bowed finger extending upwardly from the lower end of said downwardly extending portion and terminating close to and below said supporting structure and below the coil, the downwardly curved extending portion of the tooth passing adjacent the side of the arm and all parts of the tooth from the eye to the free terminal of the finger being free to yield in any direction when subjected to pressure.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
